Here's a link to the guide which includes a download link for the virtual monitor. https://www.amyuni.com/forum/viewtopic.php?t=3030
You don't have to have anything plugged into HDMI.
The one thing I did in the end which allows me to fully shut down the PC and start it back up when I want, and still have the monitor attached, is to use TaskScheduler.exe to run "usbmmidd.bat" at highest privilages as soon as possible whether I'm logged in or not.
Cheers and make sure to tell others about this if it ever comes up!
After the first step above is executed, you can modify the list of supported resolutions by changing the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WUDF\Services\usbmmIdd\Parameters\Monitors
Up to 10 resolutions can be defined through this registry key. The keys should be named from "0" to "9". The (Default) registry value defines the default monitor resolution.
Note that the list of resolutions can also be found in the usbmmidd.inf file that accompanies the printer driver. The inf file should not be modified in any way, otherwise the virtual display driver digital signature is invalidated.
